Step-by-step explanation:
We know
Membership cost per month = $20
Price of a slice of pizza for members = $2
How much would Alang have to pay the pizza shop if he bought 17 slices of pizza this month?
The total cost of Alang on 17 slices of pizza = membership cost per month + prices of 17 discounted pizza
$20 + $2(6) = $32
What would be the monthly cost for a slice of pizza
The monthly cost of Alang a slice of pizza = membership cost per month + price of 1 discounted pizza
$20 + 2 = $22

a spherical glass bulb measures 31.5 mm in diameter. what is the volume of the bulb in cubic centimeters?
The volume of the spherical glass bulb is approximately 14.1 cubic cm.
To find the volume of a spherical glass bulb, we can use the formula for the volume of a sphere:
[tex]V = 4/3 * pi * r^3[/tex]
Where V is the volume, pi is a mathematical constant (approximately equal to 3.14), and r is the radius of the sphere.
We know the diameter of the bulb is 31.5mm and to find the radius of the sphere, we divide the diameter by 2.
So, radius (r) = 31.5mm / 2 = 15.75mm
Now we can substitute this value into the formula for the volume of a sphere:
[tex]V = 4/3 * pi * (15.75mm)^3[/tex]
We can convert the value of radius from mm to cm by multiplying it by 10^-3
[tex]V = 4/3 * pi * (15.75 * 10^{-3})^3[/tex]
Now we can calculate the value of V
V ≈ 14.1 cubic cm
Therefore, the volume of the spherical glass bulb is approximately 14.1 cubic cm.

A memberhip to Gym A cot $200 to ign up and $10 per month. Gym B’ memberhip cot $0 to ign up and $60 a month. Write an equation to find out how many month you can belong to each gym for it to cot the ame at both place
So, the equation to determine the number of months is 200 + 10x = 0 + 60x.
Let x be the number of months you can belong to each gym for it to cost the same at both places.
The equation to determine the number of months is:
200 + 10x = 0 + 60x
To solve for x, we can subtract 200 from both sides of the equation:
10x = -200
And finally, we divide both sides by 10:
x = -20
Therefore, you can belong to each gym for -20 months for it to cost the same at both places. But since month are positive numbers, x=-20 is not a solution. Therefore, the statement is not true, the cost will never be the same for both gyms.

Express the shear function in terms of x, where x is in meters, for the beam in (Figure 1). Express your answer in terms of x.
A perpendicular force is applied to a beam. The maximum force is 12 kN. The resulted shear function is S(x) = - 2x²
When a perpendicular force is applied to static material (in this case, a beam), shearing forces occur.
Shearing force is calculated as the algebraic sum of all transverse forces acting on either side of a beam or frame section.
First, look at the ratio between forces (in y-direction) and x.
y/x = 12/3
y = 4x
Let S(x) = shear function.
Applying Newton's first law on y-axis:
∑Fy = 0
S + x · 4x · 1/2 = 0
S + 2x² = 0
S = - 2x²
Therefore, the shear function is S(x) = - 2x²

The value of upper quartile is, 300.
The value of 7th decile is, 250.2.
The value of 35th percentile is, 100.
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
We have to given that;
The donations are as follows,
⇒ 50, 50, 50, 100, 100, 100, 150, 150, 200, 250, 250, 300, 300, 400, 500.
Now, We find the values as;
a) The upper quartile is,
⇒ Qₐ = a/4 (n + 1)
Here, n = 15
So, We get;
⇒ Q₃ = 3/4 (15 + 1)
= 3/4 × 16
= 12
So, Q₃ is in 12th position.
So, The value of Q₃ = 300
The value of 7th decile is,
⇒ D₇ = 7/10 (15 + 1)
= 7/10 × 16
= 11.2
Here, 11.2 is between the position 11th and 12th position which are 250 and 300 respectively.
Then, We get;
⇒ 300 - 250 = 50
Hence, The value of D₇ = 250 + 0.2
= 250.2
Now, The value of 35th percentile is,
⇒ Pₐ = a/100 (n + 1)
⇒ P₃₅ = 35/100 (15 + 1)
= 35/100 × 16
= 5.6
Here, 5.6 is between the 5th and 6th position which are 100 and 200 respectively.

each angle.
7. 21 and 22 are vertical angles. If mZ1 = (17x + 1) and m/2 = (20x-14), find m22.
8. ZK and ZL are complementary angles. If mZK = (3x + 3) and mL = (10x-4), find the
measure of each angle.
Answer:
Since 21 and 22 are vertical angles, they are congruent. Therefore, m/1 = m22.
Using the equation m/1 = (17x + 1) we can find the measure of the angle m22.
m22 = (17x + 1)
Since ZK and ZL are complementary angles, the sum of their measures is 90 degrees.
mZK + mL = 90
Using the equations mZK = (3x + 3) and mL = (10x-4) and substituting them in the equation, we can find the measure of each angle.
3x + 3 + 10x - 4 = 90
13x - 1 = 90
13x = 91
x = 7
Therefore, mZK = (3x + 3) = (3(7) + 3) = 24 and mL = (10x-4) = (10(7) - 4) = 66

Complete loss of contact between articulating surfaces. Articular cartilages are damaged, ligaments tear, and the joint capsule is distorted
This is a condition known as ankylosis, and it describes a situation in which two bones lose their contact with each other.
What is ankylosis?Ankylosis can result from a variety of causes, including trauma, infection, or degenerative joint diseases. In cases of trauma, the articulating surfaces of the bones can be damaged, leading to a complete absence of contact between the two bones. Similarly, if an infection is present, the cartilage and ligaments of the joint can be destroyed, leading to ankylosis.
Finally, in cases of degenerative joint diseases, such as arthritis, the joint's articulating surfaces can be damaged, leading to a complete loss of contact between the two bones.
The symptoms of ankylosis vary depending on the severity of the condition. In mild cases, the patient may experience stiffness, pain, and reduced range of motion in the joint. In more severe cases, the joint may become completely immobile, and the patient may have difficulty walking or performing other activities.

It is not possible to determine the number of cubes that can be shipped in this box for $7.95 without more information about the size and weight of the cubes. The weight constraint of ten pounds and the size constraint of 18 cm x 18 cm x 18 cm box only applies to the overall package and not to the individual cubes. The weight and volume of the individual cubes would need to be taken into account in order to determine how many could fit within the package while still adhering to the weight and size constraints.
The correct question should be:

Consider the weight of the cube as 2 grams.

URGENT, pls answerr!!
Answer:
15/16
Step-by-step explanation:
In a dice, there are 3 even and 3 odd numbers.
So, to calculate the required probability, we will have to calculate the probability of getting an odd number in all of them.
Probability of getting odd number in 1 dice = 3/6 = 1/2
Probability of getting odd number in 4 dice =
1/2 x 1/2 x 1/2 x 1/2 = 1/16
Therefore, probability of getting atleast one even number is 1 - 1/16 = 15/16
15/16 is the answer.
Pls mark as brainliest. Cheers
Solve for X, Leave in simplest radical form.
By the concepts of trigonometric ratios, the value of x in the right angle triangle is 1.
What are trigonometric ratios in terms of a right-angle triangle?We know a right-angled triangle has three sides they are -: Hypotenuse,
Opposite and Adjacent.
We can remember SOH CAH TOA which is,
sin = opposite/hypotenuse, cos = adjecen/hypotenuse and
tan = opposite/adjacent.
If we take the reference angle of 60°, Then the hypotenuse is x and the adjacent is 2.
We know, cos = adjacent/hypotenuse.
Therefore,
cos60° = 2/x.
x = 2cos60°.
x = 2×1/2.
x = 1.

How to find the volume of a cylinder?The formula for the volume of a cylinder is;
V = πr²h
Where;
V is volume
r is radius
h is height
We are given;
Radius(r) = diameter/2 = 2.5/2 = 1.25 ft
Height(h) = 5 ft
Thus;
V = π * 1.25² * 5
V = 24.53125 ft³
There are approximately 7.48 gallons of water in a cubic foot, therefore;
Number of gallons in 24.53125ft³ = (24.53125 * 7.48)/1
Number of gallons = 183.49 gallons

Answer: 183.49 gallons (D)
Step-by-step explanation:
Okay you are trying to find how many gallons of water the water cooler can hold.
So start by using the formula for the volume of a cylinder.
V = πr^2h
First find the radius, which is half the diameter.
The diameter is 2.5 so divide that by 2 to find the radius.
2.5/2 = 1.25
Now that you know the radius, times it by itself:
1.25 x 1.25 = 1.5625
Now multiply 1.5625 by the height, which is 5.
1.5625 x 5 = 7.8125
Now multiply 7.8125 by 3.14
7.8125 x 3.14 = 24.53125
And finally, multiply 24.53125 by 7.48
24.53125 x 7.48 = 183.49375 gallons
Now round to the nearest hundredth:
183.49 gallons

Assume the random variable x is normally distributed with mean u = 50 and standard deviation o = 7. Find the indicated probability. P(x >43) P(x>43)= Assume the random variable x is normally distributed with mean u = 81 and standard deviation = 4. Find the indicated probability P(70
The indicated probability P(x >43) of the random variable x normally distributed is 0.8414.
What is Normal Distribution?Abraham de Moivre, a Frenchman, was the first to recognize the normal distribution (1667-1754). The curve was later developed further and its equation was developed by Carl Friedrich Gauss (1777–1855); for this reason, it is also more generally referred to as the "Gauss bell" or "Gaussian distribution."
Any point (x) from a normal distribution can be converted to the standard normal distribution using the formula z = (x-mean) / standard deviation (z).
Given:
Mean u = 50
Standard Deviation o = 7
To find the probability P(x>43),
= [tex]P(\frac{x - 50}{7} > \frac{43 - 50}{7} )[/tex]
= [tex]P(z > -1) = 0.8414[/tex]
